Closed-loop Electromagnetic Forces Calculations and Controls of a Non-contacting Industrial Steel Plate Conveyance System

摘要

An on-line electromagnetic force calculation scheme, along with the appropriate closed-loop control design onto a linear induction machine prototype, will be developed for practical industrial steel plate conveyance system applications. Through accurate signal detections and appropriate feedback controls, real-time balanced lift and propulsive forces can be stably generated onto the secondary mover (steel plate) of the motor, and the objectives of non-contacting conveyance system structures can be achieved.
